Revival versus Revelations
The titles share a prefix and almost nothing else. I checked the film article so I would not describe the wrong work.
What I checked
Wikipedia records Hellraiser: Revelations as a 2011 direct-to-video entry with a poor reception. It is not on Steam. The game's store page does not mention it. If your search box corrected 'reval' to Revelations, and you wanted lock codes, you want the codes page instead.
If you wanted the game
Use the download page for stores and the walkthrough hub for the route. Nothing on the Revelations film page will open a keypad in the game.
Questions
Does the game continue Revelations?
No source I used says that. The publisher's anchor is the 1987 film.
